The Steelcase leap is the best when it comes to the high end office chairs. I had aerons for the longest time but the non adjustability is not worth the price paid.
For me it was a tossup between the Herman Miller Aeron ($450 refurb) and Steelcase Leap 2 ($250 refurb).
I picked the Leap 2 and never looked back. Fabric seats, more adjustability, very sturdy and cheaper refurb prices (I think at full price it's similar to the Aeron).
The Aeron has that coolness factor which the Leap 2 doesn't (Leap 2 looks very conventional) but it has been a sturdy chair throughout the pandemic to now.
Also what I forgot to mention is that the back of the Leap is flexible like the even more expensive than that Aeron chair: the Embody. So basically you get a substantially better chair than both the Aeron and the Embody for a better price. I feel Herman Miller is coasting a bit on the Aeron being so iconic.
The leap is great, I used to have one at a previous office. The "Think" is nice too, which is what I have now. I bought it at the start of the pandemic, "renewed" from Amazon, which cut the list price in half.
